aptitude --purge

I find no way in aptitude to
# aptitude install telnet-ssl
Reading package lists... Done <- Get rid of these messages, and
The following NEW packages will be installed:
telnet-ssl
The following packages will be REMOVED:
telnet{a} <- also purge instead of removing. I.e., nothing like
APT::Get::Purge. The undocumented --purge doesn't work like apt-get's.
One must follow with a
# aptitude purge ~c
to clean up the mess.

You are not right. Purge is {p}, not {a}.

Yes, I'm saying I want a {p} but all I can get is an {a}. This is bug
486454 apparently, which is quite easy to reproduce by installing back
and forth telnet and telnet-ssl back and forth back and forth.

There is no working -o option that will allow you to install and purge
the residue in one single command. You need to clean up the config
files with a second aptitude command. Note, I only use the command
line and not the curses interface.

I never figured out what's going on in #486454, but this is a
completely different problem. That bug says that unused packages
aren't being removed at all from a user's system; I don't know why.
You are asking for aptitude to support purging packages that are
already being removed.

There is no --purge option, which is presumably why it doesn't work.
The closest thing to it is --purge-unused, which causes packages being
removed because they're unused to also get purged.

According to the apt-get manual page, --purge purges anything that is
being removed. The only thing I can think of that gets you close to
what you want is "aptitude -s install telnet-ssl '?action(remove)_'",
but I don't think that is really adequate (it won't handle stuff that
gets removed due in interactive dependency resolution, for instance).

I thought at first that I could just set all the stuff being removed
to be purged as well, just before aptitude shows its prompt. But
that's not right either: the user should be able to cancel individual
purges and have that stick. So I guess the only way out is to hack the
backend so that when a hypothetical Aptitude::Purge is enabled, it
flicks packages to "purge" when they're first marked for removal and
not afterwards.

I suppose you could file a wishlist bug asking for this feature to be
added.

If I understand you correctly, you want all automatically removed
packages to get purged instead. I have the following in my
~/.aptitude/config to do just that:

Aptitude "";
Aptitude::Purge-Unused "true";

Also, you probably need

Aptitude::Purge-Unused true;

Won't work: telnet-ssl is being purged by the greedy dependency
resolver (telnet conflicts with it), not because it's unused.

Not Read The Fine Manual?

man 8 aptitude
